Critical Patches Issued for Microsoft Products, February 08, 2022

DESCRIPTION:
Multiple vulnerabilities have been discovered in Microsoft products, the
most severe of which could allow for remote code execution in the
context of the logged on user. Depending on the privileges associated
with the user, an attacker could then install programs; view, change, or
delete data; or create new accounts with full user rights. Users whose
accounts are configured to have fewer user rights on the system could be
less impacted than those who operate with administrative user rights.

IMPACT:
Multiple vulnerabilities have been discovered in Microsoft products, the
most severe of which could allow for remote code execution.

Successful exploitation of the most severe of these vulnerabilities
could result in an attacker gaining the same privileges as the logged-on
user. Depending on the privileges associated with the user, an attacker
could then install programs; view, change, or delete data; or create new
accounts with full user rights. Users whose accounts are configured to
have fewer user rights on the system could be less impacted than those
who operate with administrative user rights.

RECOMMENDATIONS:
We recommend the following actions be taken:

Microsoft to vulnerable systems immediately after appropriate testing.
* Apply the Principle of Least Privilege to all systems and services,
and run all software as a non-privileged user (one without
administrative rights) to diminish the effects of a successful attack.
* Remind all users not to visit untrusted websites or follow links/open
files provided by unknown or untrusted sources.
